SHEET INSERTER. I

Application filed May 4,

This invention relates to certain new and useful improvements in sheet inserters of the type illustrated in Letters Patent No. 1,640,132, issued Henry G. Miller, August 23, 1927.

One objectionable feature to that type of sheet inserter illustrated in said Letters Patent is that the sheets cannot be shifted a single opening due to conflict between the posts of the inserter and the binder impaling prongs or rings and this invention has as an object the provision of an improved sheet inserter whereby the sheets may be shifted any number of openings irrespective of the inserter posts registering with the binder rings. P

A more specific object of: this invention resides in the provision of an improved sheet inserter including a plate having a notch or slot in its inner edgefor each sheet perforation and posts at the inner ends of certain apertures, the posts telescoping over the binder impaling prongs or retaining rings when in alignment therewith. v

With the above and other objects in view which will appear as the description proceeds, my invention resides in tne novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claims.

In the accompanying drawings, I have illustrated one complete example of the physical embodiment of my invention constructed according to the bestmode I have so far devised for the practical application of the principles thereof, and in which:

Figure 1 is a fragmentary perspective view of a loose leaf binder of the ring type illustrating the manner of using my improved sheet inserter therewith;

Figure 2 is a plan view of the inserter with parts broken away andshowing a series of sheets carried thereby;

Figure 3 is a transverse sectional view through the inserter on the plane of the line 33 of Figure 2;

Figure 4 is an enlarged, fragmentary, detail view, partly in section and partly in elevation, taken through F igure 2 on the plane of the line 44, and

1928. Serial No. 275,150.

Figure 5 is an enlarged, fragmentary view taken through Figure t on the plane of the line 5-5.

Referring now particularly to the accompanying drawings, in which like numerals designate like parts throughout the several views, 5 represents a loose leaf binder of any design or construction having a series of impaling prongs or retaining rings 6 adapted to be split along a central longitudinal line to permit the insertion of or removal from the binder of a series of sheets 7 having equi-spaced. perforations 8 along their inner edges through which the rings pass.

The sheets 7 are adapted to be so arranged in the binder that certain data on their 'upper edge is visible at all times, this being accomplished by having their upper edges staggered, and frequently it is necessary to shift one or more of the sheets in the binder for the insertion of one or more additional sheets without disturbing the-visible feature of the record.

In the structure illustrated in the Letters Patent before referred to, an improved sheet inserting device is illustrated for accomplishing this purpose but it is open to the objection that the sheets cannot be shifted to have the, binder impaling prongs engage in the apertures registering with the posts of the inserter and this invention contemplates provision of an improved inserter whereby the posts thereof telescope with the impaling prongs or rings of the binder sothat the sheets may be readily slid over the retainer rings from the posts of the inserter and .vice

versa.

The inserter consists of a base or plate 9 having a series of regularly spaced notches or apertures 10 communicating with its inner edge and spaced apart a distance equal to the spacing of the apertures 8 of the sheets so as to register therewith in the manner illustrated in Figure 2. Posts 11 are mounted in the inner ends of certain of the apertures 10 to engage in certain of the perforations 8 of the sheets and maintain the notches, the lower ends of the posts being i flanged, as at 12, to overlie the plate 9 to plate 9 positioned thereunder facilitate the riveting .or otherwise securing of the posts to the plate, as at 13. The upper ends of the posts are preferably biased or beveled inwardly and downwardly to eliminate the presentation of abrupt shoulders obstructing the movement of the sheets thereover.

- An auxiliary or retaining plate 14 is adapted to be disposed over plate 9 with its outer marginal edge 15 spaced inwardly of the inner ends of the notches 10 being retained in position by studs 16 riveted or otherwise secured to plate 9 and being engageable in apertures 17 in the auxiliary plate. In using the device, the covers of thebinder 5 are opened with the sheets to be shifted topmost and the leaves to be shifted are partly slid up on the-rings 6 and the with the notches receiving the rings 6 centering the notches 10 with the apertures of the sheets. The sheets to be shifted are then slid back over the rings onto plate 9, the .posts 11 entering the registering sheet apertures. The retaining or auxiliary plate 12 then placed over plate 9 and the sheets thus clamped against disalignment with respect to the notches 10, after which the rings 6 aresplit and the inserter with the sheets clamped therebetween removed and shifted longitudinally the desired number of apertures, the post 11 telescoping with the binder rings should they register therewith, vasclearly shown in Figure 1. The tapering or biased ends of the posts assure the engaging of the sheets thereover and eliminate the presentation of abrupt shoulders thereto.

From the foregoing description taken in connection with the accompanying drawing it will be readily apparent to those skilled in the art to which an invention of this character appertains that I provide a novel and improved sheet inserter which may be readily handled by any novice with absolute assurance that the sheets will be arranged in the binder in their regular sequence or order and that the device can be cheaply constructed and that the sheets may be shifted any number. of apertures irrespective of the relation of the binder impaling prongs with respect to the inserter posts.

What I claim-as my invention is:

1. A sheet inserter for a loose leaf binder having impaling prongs and sheets provided with series of spaced perforations through which the prongs pass, said inserter comprising a plate havlng a series of recesses to register with the sheet perforations and receive the prongs of the binder, and

channelled post members registering with the plate recesses and'engageable in registering perforations of sheets placed on the impaling prongs registering therewith.

2. A sheet inserter for a loose leaf binder having imp aling prongs and sheets provided with series of spaced perforations through which the prongs pass, said inserter comprising a plate having a plurality of spaced posts adapted to enter registering perforations of sheets under which the plate is inserted, said plate having a series of recesses adapted to register with the sheet perforations, the said posts being tubular and registering with the adjacent recesses to telescope overthe impaling prongs engaged in the adjacent recesses.

3. A sheet inserter for a loose leaf binder having impaling prongs and sheets provided with series of spaced perforations through which the prongs pass,'saidinserter comprising a plate having a plurality of spaced posts adapted to enter registering perforations of binder sheets under which the plate is inserted, said" plate having a series of notches in one edge adapted to register with the sheet perforations, the said posts being recessed and registering with the adjacent notches to telescope over impaling prongs engaged in the adjacent notches, and an auxiliary retaining plate adapted to clamp sheets engaged over the posts between it and the first plate.
